While the actual film is rather inconsistent (though I still quite like it), Halloween IV has my favorite opening sequence outside of the Carpenter original. The scenes of rural, late October mid-west are quite striking, and just give off that Halloween vibe in a wonderful, yet creepy, way.

And a neat little piece of movie trivia: The movie had been filmed using a converted Shatner mask, like the original, but for whatever reason, they re-shot the film with the new and lamer mask. In one scene near the end, when Myers grabs and throws Loomis out of the school window, you can see the Shatner mask (they left it in the film..probably because it lasts only a second and they didn't think anyone would notice).
